DNS doesn't 'propagate' except in the very limited case of zone-transfer publication, which... nobody really relies on these days. Registrars tell you it takes 24 hours to propagate to stop you from complaining to them about your ISP's DNS caching policy. The reality is: recursing DNS servers have caches, they respect TTLs, and for the most part that means that DNS changes should fully wash through within an hour for most changes (less if you keep your TTLs shorter). |
